Abstract (en)
The present invention relates to a base station for receiving a transmitted signal which includes at least one short code which is periodically updated; the base station comprising: - a despreader for receiving and despreading the transmitted signal to output a despread signal; - a background noise estimator for obtaining a background noise estimation using the periodically updated short code; and - a decision unit, which receives the despread signal and the background noise estimate, calculates a value representing the likelihood that a short code has been detected and compares the value with a predetermined threshold; whereby the decision unit confirms the detection of the short code if the value exceeds the predetermined threshold.
